Or maybe just stop?!?

I did not say that. I was talking about the difference between real-time and forum-style communication; I didn't say there's no value in indexing both. As mentioned, Zulip supports indexing the real-time communications that occur on it, if you have them in a "web public" stream; currently that's indirect through zulip-archive, but eventually it can happen directly.

Whether a channel is private or public is something to be determined on a channel-by-channel basis.
